Description

[Detailed description of the invention] [Field of industrial application] This invention is used to reinforce containers used to store cargo and transport it by truck, ship, etc. when transporting material from one region to another. It is related to the bracelet used for.

[Conventional technology]

Box-shaped containers are commonly used to transport cargo to remote locations.

However, even if cargo is transported from one region to another, if there is no cargo to be transported when returning from the remote location, it is a waste of space to carry the box-shaped cargo on a truck or the like. In addition, when moving containers without cargo or storing a large number of containers in a warehouse etc., moving them in a cubic or rectangular shape is cumbersome, and the storage space is limited. Since it takes up a lot of space, space is wasted and it is not possible to accommodate many containers at once.

Therefore, a collapsible container as disclosed in Japanese Patent Application Laid-Open No. 199443/1983 has been developed.

[Problem that the invention attempts to solve]

This container has left and right side plates that bend inward on both sides of the top plate and bottom plate, and the shutter housed in the top plate can be moved up and down via springs, guide grooves, and rollers on the front and back sides. It can be set freely.

However, when this container is constructed into a box shape by standing up the left and right side plates and pulling down the shutter, there is a risk that the container will deform if an external load is applied during transportation.

In other words, the movable shutter is relatively thin and bendable, and the upper and lower ends of the left and right side plates are connected by pins, and the center can be bent inward, so it can resist pressing forces from the top, bottom, left and right, or diagonal directions. If this occurs, for example, when multiple containers are stacked upward, a downward load and a load due to lateral shaking may be applied, causing the lower container to deform.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a collapsible container brace that prevents the container from being deformed even when external loads are applied.

[Means for solving problems]

In order to achieve the above purpose, the configuration of the present invention is as follows:
It consists of a long frame and a locking frame telescopically inserted into the long frame, both of which are driven to expand and contract with a handle, and the hooks of the locking frame can be attached to and removed from other pins. It is something to do.

[Effect]

Rotation of the handle causes the locking frame to slide within the elongated frame.

〔Example〕

An example of implementing the present invention will be described below with reference to the drawings.

The container that uses the breather of this invention is shown in Figure 1.
As shown in FIG. 2, it has a cubic configuration including a top plate 1, a bottom plate 2, bendable left and right side plates 3, 3, and front and back shutters 5.

The left and right side plates 3, 3 are two rigid plates 4, upper and lower.
a and 4b, and the upper plate body 4a has a hinge part 6.
Similarly, the lower plate 4b is rotatably connected to the bottom plate 2 via a hinge part 7, and the upper and lower two plates 4a and 4b are connected to a central hinge part 8, hinged via 8;
The two plate bodies 4a and 4b are configured to be bent inward via central hinge parts 8 and 8.

Both sides of the front shutter 5 and the rear shutter 5 are inserted into guide grooves provided in the frame 9 of the left and right side panels 3, and are guided via rollers so that they can move up and down. When storing cargo in the container, the front shutter 5
is raised and pulled down during transportation to lock onto the bottom plate 2 side.

When folding the container, use the front shutter 5.
and the rear shutter 5 are pulled up and housed in the top plate 1, and as shown in FIG.
The center hinge parts 8, 8 and the upper and lower hinge parts 6, 7
bend inward through.

The front and rear shutters 5, 5 are always biased in the upward direction by springs installed inside the top plate 1, and when the shutters 5, 5 are opened, they are pulled toward the top plate 1 side by the springs, and the rollers and guide grooves You will be guided up.

Locking mechanisms 10, 10 are provided adjacent to the central hinge portions 8, 8 of the left and right side plates 3, 3, and the locking mechanisms 10, 10 consist of a case 11 and a wedge 12, and the wedge 12 is driven into the case 11. At this time, the hinge parts 8, 8 are locked, so that the hinge parts 8, 8 are not bent even if an external force is applied.

Seal devices 13 are provided above and below the joints between the front and rear shutters 5, 5 and the left and right side panels 3, 3 to prevent rainwater from entering.

A shutter locking device is provided at the end of the bottom plate 2 facing the shutters 5, 5, and when the shutters 5, 5 are pulled down, the shutters 5, 5 are held via this locking device and the locking device is released. Then, the shutters 5, 5 are pulled up by the springs inside the top plate 1.

Upper reinforcing devices 14, 14 are removably provided between the top plate 1 and the left and right side plates 3, 3, and the bottom plate 2
A lower reinforcing device 15, 1 is installed between the left and right side plates 3, 3.
5 is provided.

The upper reinforcing devices 14, 14 are composed of telescopic braces according to the present invention.

As shown in FIG. 3, the brace consists of a hollow elongated frame 16 and a locking frame 17 telescopically inserted into the elongated frame 16, and the base end of the brace is pivotally attached to the top plate 1. The tips are adapted to be removably hooked onto pins 18, 18 provided on the frames 9, 9 of the left and right side plates 3, 3.

A long hole 19 is formed along the longitudinal direction on the base end side of the long frame 16, and a shaft 2 is inserted into this long hole 19.
0 is movably inserted, and this shaft 20 is connected to a forked support frame 21 fixed to the front of the top plate 1. This allows the elongated frame 16 to move within the support frame 21 by the length of the elongated hole 19 and to rotate about the shaft 20.

An opening 21 is formed on the distal end side of the elongated frame 16, and a bracket 22 stands up at a position close to the opening 21. A distal end of a handle 24 is rotatably attached to the bracket 22 via a shaft 23. It is pivoted. Furthermore, a curved pin locking portion 25 is formed at the lower end of the long frame 16.

On the other hand, the locking frame 17 is made of a single plate or a bifurcated plate, and a hook 26 is formed at the tip thereof facing the pin locking portion 25.

A bracket 27 stands up near the top of the locking frame 17, and this bracket 27 projects upward from the opening 21 of the elongated frame 16 and can move within the range of the opening 21 in the longitudinal direction. ing.

One end of two links 29 is pivotally attached to the bracket 27 via a shaft 28, and the other end of the link 29 is pivotally attached to the handle 24 via a pin 30.

Therefore, when the handle 24 is rotated in the direction of the hook 26 using the shaft 23 as a fulcrum, the link 29 rotates in the same direction around the pin 28 in conjunction with the handle 24, and at this time the bracket 27 is pushed forward and engaged. The locking frame 17 is pushed out, and as a result, the total length of the long frame 16 and the locking frame 17 becomes longer. On the other hand, when the handle 24 is rotated in the opposite direction from this state, the bracket 27 and the locking frame 1
7 is retracted and the length of the breath is shortened.

Bracelet receiving member 3 on the front and back center of the top plate 1
1 is provided, and a hook 26 is hooked onto this receiving member 31 when the brace is not in use. When in use, the elongated frame 16 is moved backward through the elongated hole 19 to remove the hook 6 from the receiving member 31, and then the elongated frame 16 is rotated downward about the shaft 20, and the handle 24 is further rotated. Then, the locking frame 17 is pulled out, and the hook 26 is opposed to the pin 18 of the frame body 9.

Next, when the handle 24 is rotated to the original position, the locking frame 26 is pulled into the elongated frame 16, and the length of the breath is shortened, and at the same time the hook 26 is
is hooked to pin 18, and pin 18 is hooked to hook 26.
and the pin locking portion 25.

For this reason, braces are installed diagonally between the top plate 1 and the left and right side plates 3, 3 to reinforce both.
and in the vertical and lateral directions with respect to the left and right side plates 3, 3,
The container does not deform even if a diagonal load is applied. As a similar reinforcing device 15, braces are installed diagonally at the corners of the bottom plate 2 and the left and right side plates 3, 3.

The structure of the brace is exactly the same as in the previous case, but the base end of the brace is pivotally attached to the groove frame 32 provided at the end of the bottom plate 2 via a shaft 33, and when not in use, the brace is attached to the groove frame 32. When in use, it rotates upward and engages with the pin 18a of the frame 9, reinforcing the space between the bottom plate 2 and the left and right side plates 3, 3.

[Effect of idea]

According to the present invention, there are the following effects.

Since the locking frame is telescopically inserted into the elongated frame, the length of the brace installation position can be adjusted arbitrarily.

It is easy to operate because it expands and contracts by operating the handle. In other words, it requires less operating force and can increase speed.

Since the locking frame is provided with a hook, the hook can be hooked onto the pin when in use, and can be removed from the pin when not in use, so the bracelet itself does not get in the way.

Since the long frame and the locking frame are connected through the link and handle, each part does not come apart, a standardized brace can be obtained, and it is convenient to carry and store.
